To all whom it may concern.-

Be it known-that I, SOREN H. MADSEN, a citizen of the United States, residing at-Hayward, countyof Alameda, State ofzCalifornia, have invented an Improvement in; Brakes and Bells forvehiclesy'andl hereby declare the following to be a full, clear, and exact and bell mechanism for vehicles; and it consists of the partsiand;theconstructions and 'after'describeand claim.

s here shown, the clamp consistsof oppositely-curved.ho0ks,-one of which is adapted to clasp one side and the other the opposite side of the fork head or sides, as shown, and by means of an'ut 4 the clamp may be tighten'ed as firmly as may be desired. The op- Y formed to receive the journal pins or shafto posite. end'of the pl'ateisforkedpr suitably of a roller,- the ends of which consist of steel bands orsleeves suitablylclamped or secured the roller,formed of the elastic interior and outer surface ofycords, will contact withthe' central portionis of. lessjdiarneter'than thetire of the bicycle when the two are. forced into contact, and the roller will be caused to rotate as long as thetwo are =1maintained incon tact.

- Thebrake-lever is suitably fnlcrumed upon 8s .witha single pin.-.- The plate 6 may be normally raised to keep the shoe 7 out of contact I o be adjusted. From the part 13 theypin 15 the handle-bar, so as to be within easy reach of the rider. 7

Any of the various forms of brake-levers or connecting devices may be easily applied to this apparatus. I have here shown the brake device as being so fixed to the front portion of the machine that the brake-roller is located just in rear of the bicycle front forks and beneath the lower bar of the frame; but it will be understood that, if desired, the position may be reversed and the roller press upon the wheel-tire in front of the forks, in which case the pivot 5 would be at the rear instead of at the front.

The pressure-plate 7 is so located in either case as to be-in front of a line passing through the axis of the roller and the point of contact with the wheel-tire, experience showing that this is the best relative position for the most efficient braking effect.

16 is a bell supported from the plate 3 by an arm secured thereto and projecting so that the bell may be fixed to the arm, preferably at the front.

17 is a spring-pressed lever suitably journaled upon a frame 3 and carrying at one end a head 18, which is adapted to strike the bell. The opposite end of the lever extends to a point where it will be engaged by a lug 19, carried by the brake-roller A. This pin or lug engages the end of the hammer-lever at each revolution of the roller A, thus lifting the hammer, and when released from the pin 19 a spring 20 acts to move the lever and cause the hammer to strike the bell. Thus by a light pressure upon the brake-lever the rod 14 will act to depress the whole device, so that the roller will contact with the wheel with a light rolling movement, which will act to sound the bell without sensibly checking the movement of the machine. By a further heavier pressure the roller is forced more firmly into contact with the wheel, and at the same time the pressure-plate 7 is forced into contact with the top of the roller with as much pressure as may be desired, thus checking or stopping the wheel and the machine to which it is attached.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination in a bicycle-brake of clamps, means for securing them to the bicycle-head, a plate fulcrumed with relation to said clamps, and having a forked outer end, a roller journaled between said forks and including a central core, an elastic sleeve surrounding the core and metal bands upon the ends of the core, said sleeve having the portion between the bands of less diameter than said bands, and provided with a spiral wrapping of cords, a pressure-plate having shoes adapted to press upon the metal end bands of the roller in opposition to the pressure of the central portion of the tire, a spring acting upon said plate to hold the shoes normally out of contact with the roller, a guided rod connected to the plate, and extending upwardly, and a brake-lever for actuating the rod.

2. The combination in a bicycle-brake of a clamp, means by which it is secured to the bicycle-fork, a plate pivotally mounted at one end and having'its other end forked, a roller journaled between said forks and including a core having a reduced central portion and an elastic sleeve fitting said reduced portion, and metal bands on the ends of the core, means whereby the roller is pressed into contact with the tire, a pressure-plate to engage said end bands ofthe roller and means for actuating said pressure-plate, a bell carried by the first-named plate, ahammer fulcrumed to the plate, and a pin carried by the roller and engaging said arm, and causing the hammer to act upon the bell.

3. The combination in a bicycle-brake of a clamp, means by which it is secured to the bicycle-fork, aplate pivotally mounted at one end and having the opposite end forked, a roller mounted in the forked end of the plate having inelastic ends and an elastic intermediate portion to be forced into contact with the tire, a fulcrumed pressure-plate having shoes to engage the inelastic ends of the roller and means for actuating the pressure-plate to press the elastic portion of the roller into contact with the tire, a bell and its actuatinghammer, and a pin carried by the roller for actuating the hammer substantially simultaneously with the application of the brakeroller to the tire.

4. In a bicycle-brake the combination of a plate pivotally mounted at one end and having a forked opposite end a roller mounted in said forked end and comprising a core the central portion of which is of less diameter than the ends, metal bands upon said ends and an elastic sleeve upon the reduced central portion, cords wound transversely around said sleeve between said ends and forming the bearing-surface of the roller, a pressureplate fulcrumed at one end and carrying a shoe at the other end, to engage said metal bands, and a means for depressing the plate to cause it to force the corded surface of the roller into contact with the wheel-tire.

5. The combination in a bicycle-brake of a clamp, two levers, one above the other and independently movable, and a single axis about which both levers are movable, a roller journaled in the lower lever and adapted to press upon the Wheel of the machine, said roller having a core with reduced central portion and metal bands upon the ends, and a yielding surface upon the reduced portion, a shoe carried by the upper lever, and adapted to press upon the end bands of the roller, an interposed spring by which the levers are normally separated, a rod connected with the upper lever and means for applying pressure whereby the roller is first brought into confact with the wheel, and the shoe subsequently caused to press upon the roller.

6. The combination with a bicycle of a ing-with said lever, anda means for applying clamp, superposed levers fulcrumed thereto, pressure through the upper lever whereby the a roller journaled in the lower lever and roller is first placedin contact with the wheel .15- adapted to contact with the wheel, saidroller to sound the bell, and a further pressure including a central core with a reduced porforces the shoe-into contact with the roller.
